I purchased this FCONEGY (FC600) from another seller through Revain in August 2021. The exact model you see here, well, it was never used, of course until this week when it was found to have lost its charge, even though I charged it as instructed. Nonetheless, now after trying to recharge it again, it doesn't. approximately 3/4 of a year of life makes this a disappointing buy for me. Especially since I never got a use out of it. Even the light did not offer a ray span to be useful. I can say, its design is portable and featured to be safe.
